In the United States, abortion is a divisive issue in politics and culture wars. Prior to the mid-19th century, English common law formed the basis of abortion law in the colonies and the early Republic.
Connecticut was the first state to regulate abortion in 1821; it outlawed abortion after quickening, the moment in pregnancy when the pregnant woman starts to feel the fetus's movement in the uterus, and forbade the use of poisons to induce one post-quickening. Many states subsequently passed various laws on abortion until the Supreme Court of the United States decisions of Roe v. Wade and Doe v. Bolton decriminalized abortion nationwide in 1973. The Roe decision imposed a federally mandated uniform framework for state legislation on the subject.
